To a mixture of 4-(4-aminophenoxy)pyridin-2-amine (101 mg, 0.5 mmol) and 1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid (118 mg, 0.51 mmol) in DCM (5 mL) was added EDCI (115 mg, 0.6 mmol) and HOAT (13.6 mg, 0.1 mmol). The reaction was stirred at 45° C. for 3 hours, and then quenched with water (20 mL). The organic phase was separated and concentrated in vacuo. The residue was purified by a silica gel column chromatography (DCM/CH3OH (v/v)=20/1) to give the title compound as a light grey solid (110 mg, 49.2%).
